Local path repair in a wireless deterministic network

A method, comprising:

• establishing an initial path in a wireless deterministic network between a source and a destination through one or more intermediate nodes based on a set of predetermined timeslots to communicate packets between adjacent nodes in the initial path, with the wireless deterministic network being a low power lossy network, with each of the source, the destination, and said one or more intermediate nodes being a low power lossy network node;
• communicating packets over the initial path from the source and destination through said one or more intermediate nodes using the set of predetermined timeslots;
• informing at least one node of said one or more intermediate nodes of a required metric including an absolute time value, a receiving timeslot for receiving a packet from a prior node in the initial path, or a sending timeslot for sending a packet to a next node in the initial path;
• locally reconfiguring the initial path from the source to the destination replacing a plurality of particular intermediate nodes of said intermediate nodes with a plurality of replacement nodes in the wireless deterministic network that are not part of the initial path, wherein the new path meets required metric.

A wireless deterministic network node, comprising:

• one or more radio interfaces configured to receive a packet during a receiving timeslot and to send the packet during a sending timeslot in communicating packets along a communications path in a wireless deterministic network that is a low power lossy network;
• memory;
• and
• one or more processing elements;
• wherein the wireless deterministic network node is a low power lossy network node configured to:
• advertise a request to be replaced in the communications path by another node in the wireless deterministic network, with the request including advertising the receiving timeslot and the sending timeslot;
• select a replacement node from one or more responses received from one or more other low power lossy network nodes in the wireless deterministic network, with said one or more other low power lossy network nodes including a replacement node;
• and
• notify the replacement node to assume the role of the wireless deterministic network node in the communications path of receiving a particular packet during the receive timeslot and sending the particular packet during the sending timeslot.
